What is the nature of the roots of the equation \(3x^2+6x+3=0\)?

Answer and explanation

Correct answer: Two real and equal

Here, \(a=3, b=6, c=3\). The discriminant is \(D=b^2-4ac=6^2-4(3)(3)=0\). When \(D=0\), a quadratic equation has two real and equal roots. In fact, \(3x^2+6x+3=3(x+1)^2\), so both roots are \(-1\). Exam tip: remember that \(D=0\) indicates equal real roots.
